BREAKER FLASHOVER 1(4)
The detection of the breaker flashover is based on the following condition:
1.
Breaker open,
2.
Voltage difference drop, and
3.
Measured flashover current through the breaker.
Furthermore, the scheme is applicable for cases where either one or two sets of three-phase voltages are available across
the breaker.
